nded for students of any age (but the younger the better) that leads to the understanding of everyday phenomena. Children are often motivated to devise their own experiments after getting their curiosity whetted by these simple experiments into the properties of air, water, magnets, pendulums, levers, light, and heat. Most of the experiments can be done easily in the home with a few requiring apparatus that can be readily assembled. Through doing the experiments students acquire a considerable amount of scientific knowledge which will stand them in good stead in their future studies.
